Container for storing refrigerated liquids

Abstract

A container is disclosed for storing refrigerated liquids, in particular for liquefied gases, which comprises a steel reinforced concrete outer container and a steel inner container inserted into the outer container, where the steel inner container rests on an insulation and where an annular interspace is present between the outer circumference of the inner steel container and the inner circumference of the outer container. The interspace can be fully or in part of its thickness filled with insulating materials. In order to prevent the liquid pouring in a gush into the interspace and causing locally high loads acting on the steel reinforced concrete container upon a cracking of the steel inner container, several gush braking bodies protruding into the interspace are disposed at the inner circumference of the outer container and/or at the outer circumference of the inner steel container, which bodies extend in radial direction about one third of the width of the interspace, and which preferably reach only to about two thirds of the total height of the interspace and which according to a preferred embodiment are provided with a triangular cross-section.

What is claimed as new and desired to be protected by Letters Patent is set forth in the appended claims. 
     
       1. Container for storage of refrigerated liquids comprising a concrete outer container;   an insulation disposed on the bottom of the outer container,   an inner steel container resting on the insulation and disposed inside the outer container for providing an annular interspace between the inner wall side of the outer container and the outer wall side of the inner container;   insulating material filled into the interspace; and   at least two gush braking bodies attached to either the outer wall side of the inner container and/or to the inner wall side of the outer container and protruding into the interspace, wherein the exposed angle between the tank and the gush breaking body is 90 degrees or greater, and wherein the gush braking bodies extend in radial direction to from about one quarter to one half of the width of the annular interspace between the two containers.   
     
     
       2. The container for storage of refrigerated liquids according to claim 1 wherein the outer container is constructed from steel reinforced concrete. 
     
     
       3. The container for storage of refrigerated liquids according to claim 1 wherein the outer container is constructed from prestressed concrete. 
     
     
       4. The container for storage of refrigerated liquids according to claim 1 wherein the gush braking bodies are provided as baffle plates. 
     
     
       5. The container for storage of refrigerated liquids according to claim 4 wherein an uneven number of gush braking bodies are uniformly distributed over the inner circumference of the outer container. 
     
     
       6. The container for storage of refrigerated liquids according to claim 5 where in total five gush braking bodies are provided. 
     
     
       7. The container for storage of refrigerated liquids according to claim 4 wherein the gush braking bodies reach up to about two thirds of the total height of the interspace. 
     
     
       8. The container for storage of refrigerated liquids according to claim 7 wherein an insulating layer of an insulating material is disposed at the outer circumference of the inner container. 
     
     
       9. The container for storage of refrigerated liquids according to claim 8 wherein the insulating material is a member of the group consisting of polyurethane, mineral wool, plastic foam, exploded minerals, perlite, exploded perlite and mixtures thereof. 
     
     
       10. The container for storage of refrigerated liquids according to claim 1 wherein the gush braking bodies are provided with a triangular cross-section. 
     
     
       11. The container for storage of refrigerated liquids according to claim 10 wherein an uneven number of gush braking bodies are uniformly distributed over the inner circumference of the outer container. 
     
     
       12. The container for storage of refrigerated liquids according to claim 11 where in total five gush braking bodies are provided. 
     
     
       13. The container for storage of refrigerated liquids according to claim 10 wherein the gush braking bodies reach up to about two thirds of the total height of the interspace. 
     
     
       14. The container for storage of refrigerated liquids according to claim 13 wherein an insulating layer of an insulating material is disposed at the outer circumference of the inner container. 
     
     
       15. The container for storage of refrigerated liquids according to claim 14 wherein the insulating material is a member of the group consisting of polyurethane, mineral wool, plastic foam, exploded minerals, perlite, exploded perlite and mixtures thereof. 
     
     
       16. The container for storage of refrigerated liquids according to claim 1 wherein the edge protruding from the gush braking body into the interspace is pointed at the end edge protruding into the interspace. 
     
     
       17. The container for storage of refrigerated liquids according to claim 1 wherein the gush braking bodies are provided with perforations. 
     
     
       18. A safety method for insuring the stability of containers for refrigerated liquids comprising providing an outside concrete container;   placing insulation onto the bottom of the concrete container;   setting a steel container onto the insulation in the concrete container concentrically;   disposing baffle bodies for braking gushes of refrigerated liquid attached vertically at the walls of the containers and protruding into the interspace between the containers, wherein the exposed angle between the tank and the baffle bodies is 90 degrees or greater, and wherein the baffle bodies extend in radial direction to from about one quarter to one half of the width of the annular interspace between the two containers.   
     
     
       19. The method for insuring the stability of containers according to claim 18 wherein the baffle bodies protrude from about 0.25 to 0.5 of the width of the interspace in radial direction.
